Title: Arcing detector using optical fibre with convex mirror - is relatively insensitive to interfering electric or magnetic field
Inventor: LINDGREN CARL-ERIC
IPC: G08B29/18
Filed: 1980-08-21
Abstract: Arcing in electrical equipment is detected by directing the emitted light into the end of an optical fibre (4) using a suitably sited convex parabolic mirror (5). The fibre conducts the light to a detector unit outside the compartment, where it is converted to an electrical signal and processed to give an indication or switch the equipment off. The mirror widens the field of view of the fibre from nominally 60 deg., depending on fibre diameter, to over 180 deg. The use of an optical fibre, rather than a system using an electrical conductor, makes the detector completely insensitive to the strong electric or magnetic fields which may accompany the arcing. Alternative systems may use a plane reflecting mirror or a ribbed flat surface.

Title: Clamping device for the grinding wheel of an angle grinder
Inventor: NICKE WOLFGANG DIPL ING
IPC: B24B45/00
Filed: 1981-03-20
Abstract: The invention relates to a clamping device which comprises a clamping flange and a flange nut and is intended for the grinding wheel of an angle grinder, the clamping flange and the flange nut, screwed onto a threaded journal of the grinding spindle, receiving the grinding wheel between their mutually opposite surfaces. In the case of said device, the pulling surface, directed towards the grinding wheel, of the flange nut is provided with a wear-resistant covering, the coefficient of friction of which is so low that the moment of friction between the grinding wheel and the flange nut is considerably lower than the moment of friction of the threaded connection flange nut/grinding-spindle journal (see figure). By means of this measure, it is achieved that, owing to the grinding-wheel slip which inevitably occurs when operating with the angle grinder, the flange nut is no longer carried along, but the grinding wheel slips away over the flange-nut surface directed towards it. A consequent, automatic tightening of the flange nut is thus avoided.

Title: Brake disc for disc brake devices in rail vehicles
Inventor: WIRTH XAVER DIPL ING DR
IPC: F16D65/12
Filed: 1981-05-19
Abstract: In a brake disc for disc brake devices in rail vehicles, the friction ring of which is preferably fixed in cone-centred fashion, a flange ring of the friction ring engages with its ring faces, which extend obliquely to the radial plane of the friction ring, into an annular gap of complementary design between a clamping ring and a hub ring. In this arrangement, the radially inner boundary face of the flange ring comprises a preferably cylindrical seat for a collar connected to the shaft. The clamping ring rests with a complementary clamping face against one side of the flange ring while the hub ring present on the other side and likewise in contact by a complementary face is of multi-part design, i.e. consists of a plurality of sections, preferably of equal arc length. Due to its segmental structure, the hub ring, which engages by means of a radially inward-directed projection in a circumferential groove of the shaft or shaft collar, can be removed in individual pieces from the brake disc assembly after the removal of the bolts which extend in the axial direction through the clamping ring, the friction ring and the hub ring and serve to clamp the said components. In this way, it is possible after releasing the clamping ring and the hub ring to remove the friction ring in any axial direction from the shaft, this being of particular advantage in brake devices having a plurality of friction rings.
